PLoS ONE (2013)
Odontocetes produce a range of different echolocation clicks but four groups in different families have converged on producing the same stereotyped narrow band high frequency (NBHF) click. In microchiropteran bats,…
Population structure and intergeneric hybridization in harbour porpoises Phocoena phocoena in British Columbia, Canada
Crossman, CA; Barrett-Lennard, LG; Taylor, EB
Endangered Species Research (2014)
We used variation at microsatellite loci and in mitochondrial DNA (mtDNA) to detect and quantify (1) hybridization between the harbour porpoises Phocoena phocoena and the Dall’s porpoises Phoconoides dalli and…
Updated marine mammal distribution and abundance estimates in British Columbia
Best, B. D.; Fox, C. H.; Williams, R.; Halpin, P. N.; Paquet, P. C.
Journal of Cetacean Research and Management (2015)
Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out…
Bigg’s (transient) killer whale predation on Dall’s porpoise (Phocoenoides dalli) and harbour porpoise (Phocoena phocoena)
McInnes, Josh D.; Cullen, Kelsey D.; Browne, Lynette M.; Dehalt, Annette; Templeman, Nick M.
Technical Report for the Royal British Columbia Museum (2015)
(...) Two separate predation events were documented off the coast of Vancouver Island, British Columbia between the years 2013-2014. Both predation events occurred on small cetaceans from the Phocoenidae family:…
Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)
Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)
The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…
Harbor porpoise (Phocoena phocoena) recovery in the inland waters of Washington: Estimates of density and abundance from aerial surveys, 2013–2015
Jefferson, Thomas A.; Smultea, Mari A.; Courbis, Sarah S.; Campbell, Gregory S.
Canadian Journal of Zoology (2016)
The harbor porpoise (Phocoena phocoena (L., 1758)) used to be common in Puget Sound, Washington, but virtually disappeared from these waters by the 1970s. We conducted systematic aerial line-transect surveys…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Distribution of Dall’s porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, based on T/S Oshoro Maru 2012 summer cruise data
Suzuki, Sachiko; Sekiguchi, Keiko; Mitani, Yoko; Onishi, Hiroji; Kamito, Takehiko
Zoological Science (2016)
Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62°N; however, only limited studies of its ecology…
Polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues in the blood of harbor, Dall’s and finless porpoises from the Japanese coastal waters
Ochiai, Mari; Nomiyama, Kei; Isobe, Tomohiko; Yamada, Tadasu K.; Tajima, Yuko; Matsuda, Ayaka; Shiozaki, Akira; Matsuishi, Takashi; Amano, Masao; Iwata, Hisato; Tanabe, Shinsuke
Marine Environmental Research (2016)
This study investigated the accumulation of polybrominated diphenyl ethers (PBDEs) and their hydroxylated and methoxylated analogues (OH-PBDEs and MeO-PBDEs) in the blood of harbor porpoises, Dall's porpoises, and finless porpoises…
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
Huggenberger, S.; Leidenberger, S.; Oelschläger, H. H. A.
Journal of Zoology (2016)
In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that belong to four…
